EDMOND DUBOIS, OF BRUSSELS, BELGIUM.

MACHINE FOR MAKING CIGARS.

SPECIFICATION forming part of Letters raient No. 649,537, dated May 15,1900.

Application filed October 6,

To all wiz/0m, it may con/cern:

Be it known that l, EnMoNn DUBOIS, mechanician, a subject of the King ofBelgium, residing at 102 Rue du Marais, Brussels,in the Kingdom ofBelgium, have invented new and useful Improvements in Machines forMaking Cigars, (for which applications were filed in France on September4, 1899; in Italy on September 4, 1899; in Switzerland on September 5,1899; in England on September 5, 1899; in Luxemburg on September 5,1899, granted September, 1899, No. 3,726; in I-Iungary on September 9,1899, and in Austria on September12, 1899,) of which the following is afull, clear, and exact description.

This invention has forits object a machine for making cigars which worksin such a Way as to form first the interior of the filler and then toimmediately wrap the latter in the wrapper-leaf by means of the samemechanical parts.

In the accompanying drawings, Figure 1 is a longitudinal section; Fig.2, a front view; Fig. 3, a partial plan View with a horizontal sectionof the upper tobacco-drawer of the machine. Fig. e is a front View ofthe arrangement of knife for cutting the end of the cigar. Fig. 5represents a front View of the mechanism for cutting the leaf to a pointand shows the gumming-brush.

On the frame or table A three tobaccocom partments M are superimposedhorizontally, the upper one of which is provided with a hopper N for theintroduction of short tobacco. In the middle compartment a layer oftobacco-leaf of uniform quality is introduced by the rear end, and intothe lower compartment a leaf of better orsu perior quality, but in sucha way that the leaves are not placed longitudinally, but transversely,in the compartments, as shown in Fig. 3. The compression of the leavesin transverse position in the compartments is eiected by presserbars orplungers W', which, guided on the ends of the compartments, areconnected by links IV with a lever V, which pivots on the frame or tableA and on whichA itis suiiicient to eXert any suitable pressure in orderto compress sufficiently the leaves of tobacco against a ,valve Q,arranged in front of the other ends of the compartments. The valve Q. islocated in such a way that the portion of 1899. Serial No. 732,857. (Nomodel.)

tobacco compressed projects beyond the end of the compartments to agiven extent, so as to be capable of being separated from the remainderby the action of a cutter 0 in order to be then directed by the valve(which is then turned down in an inclined position, as shown in dottedlines in the drawings) toward a series of rolling-cylinders arrangedbehind the compartments in such a way that the workman may have accessto the portion of internal tobacco or filler cut up in the longitudinaldirection of the leaves in order to' arrange the said filler on thewrapper-leaf placed in the rolling-cylinders D, which are mountedparallel to this direction in such a way that the short tobacco is heldin the midst of the filler, which is then completed by the rolling ofthe whole between the cylinders.

The cutter o, serving to separate or cut the portion of tobacco which ispressed against the portion of the valve Q by the plungers orpresser-bars W', is fixed to a frame B, guided vertically in the frame Aand held normally in its uppermost position by strong springs B, whilein order to effect the cutting it is lowered by the foot of the workmanbeing placed in a stirrup fixed at the lower end of the frame, whichthen descends with a knife and cuts off a portion of tobaccocorresponding to a ller. Further, the cutter o pivots on its frame B, sothat any cutting which may be imperfectly made on the lowering of theframe can eventually be completed by the workman operating the cutter bythe handle O'.

. Slides Q, applied to the frame B, serve to maintainin position thevalve Q during the compression and cutting of the tobacco, as duringthis operation it is pressed against the slides, while after the cuttinghas been inished the valve turns down over the slides, which thus alsoserve to raise the Valve into its normal position when they rise withthe frame. 4

The series of rolling-cylinders are arranged on the frame A similarly tothe arrangement for preparing the fillers. This set of rollers consists,essentially, of three cylinders of special construction, two of which,D, are arranged in a stationaryposition in a transverse direction to theframe in front of the Valve IOO forming the fillers, while the thirdcylinder K is arranged at the summit of the frame B, carrying the slidesQ' in such a way as to be raised and lowered with the latter at will andin the manner hereinbefore described by means of the workmans foot. Eachof these three cylinders is formed of several truncated seetionsdistributed symmetrically from the center to the extremities of eachcylinder, so as to together form perimetral lines conforming to theshape to be given to the cigar. These conical sections or rollers arenot rigid with the spindles D of the cylinders; but theyrevolve freelyand loosely on the said spindles under the action of the frictionexerted thereon by india-rubber rollers C', corresponding exactly to theform of the external lines of the rolling-cylinders-that is to say,having the form of the cigar C, which is to be manufactured between therolling-cylinders-one being situated between the two lowerrollingcylinders in the frameAand the other against the upperrolling-cylinder K in the frame B.

The india-rubber cylinders C' are rotated by means of pinions F, keyedon their axes, which pinions when the frame B is lowered by the pressureof the workmans foot are both in gear with a large spur-wheel G, whichsets them in rotation in the same direction. The spur-wheel G is drivenby means of a barrel Il, revolving freely on the shaft of the toothedwheel Gr and on which is wound a cord II', iixed to a stirrup H, adaptedto be lowered by the foot of the workman, said barrel carrying a pawlwhich engages studs G on the large toothed wheel for setting in rotationthe rolling-cylinders when the stirrup is depressed, while the pawlyields or slips under the studs when the stirrup is released for Windingup the cord, so that the toothed wheel then remains stationary. Ofcourse this is only an example of the method of operating, seeing thatthe friction-cylinders may be operated according to requirements and inany other suitable manner.

The rolling-cylinders composed of several rollers having an externalformation coinciding with the form of the cigar to be made and capableof rotating on a common axis independently one of another have theadvantage of avoiding the drawbacks resulting from variable or differentspeeds in the perimeters of cylinder-machines in general, because theperimetral speed of each of the sections or rollers corresponds exactlyto the speeds of dierent parts of the perimeter ol the cigar inrotation, so that no irregularity or tearing of the wrappers can beproduced during the rolling. For cutting the wrapper-leaf at the pointof the cigar a knife P is applied in front of the point, said knifepivoting at P under the pull of a tension-spring P at the one end andintermittent depressions exerted by a multiple cam J on the other endand also a rotary brush I, which coats the leaf lightly with gum, said brush turning around the end C of the axis of the lower india-rubbercylinder, while the cam J turns with the axis C of the upper indiarubber cylinder C', as shown in detail in front viewin Fig. 5. The

yother end of the cigar is cut off by a knife T,

which is guided in tenons T', fixed to the frame B, the upper end of theknife having a knob E to enable it to be handled.

The working of the machine may be easily deduced from the precedingdescription. After having arranged the tobacco in the compartments M inthe manner described and having compressed it against the valve Q bymeans of the plungers or presser-bars W', operated by the lever V, theworkman places the wrapper of the filler on the lower cylinders D anddepresses the stirrup B with his foot, thus cutting off the portion oftobacco in front of the valve (which latter places it on the saidwrapper) and pressing down and imprisoning the whole between the threecylindersD DD. Then the workman depresses once or twice the stirrup H,thus setting the system in rotation, as hereinbefore described, f

and finishing the filler between the rollingcylinders. Then the samefiller (or even a certain quantity of fillers thus prepared in advance)may be wrapped by the same meehanism of cylinders and in the mannerhereinbefore described, the cigars being finished by the cutterarrangements hercinbefore mentioned.

I claim as my inventionl. In combination in a cigar-making machine,rolling mechanism and feeding mechanism comprising a series ofcompartments adapted to receive tobacco of different grades, means forfeeding the tobacco from the several compartments to a common point,means for severing a predetermined quantity of the tobacco and means forconveying the same to the roller mechanism, substantially as described.Y

2. In combination,a series of compartments, a pusher adapted to bereciprocated in each compartment, a removable backing -plate adapted toreceive the pressure of said pusher to compress the tobacco, means forsevering a predetermined quantity of the compressed tobacco, rollingmechanism and means for withdrawing said backing-plate and conveying thesevered tobacco to the rollers.

In combination, a plurality of compartments pushers working therein, abackingplate, means for holding the same in place, rolling mechanismnormally out of operation and means for bringing said mechanism intooperation and removing the support for said backing-plate, said plateconveying the tobacco to said rollers.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.
